Camtasia Studio allows you to produce high definition and compact videos for the web using H.264 format simply. Two existing production presets (blog and web) and three new presets (YouTube, HD display, and Screencast.com) take advantage of the new format.
Camtasia Studio can be used in a variety of ways, including making training, presentation, and demo videos using streamlined and intuitive screen recording software. It supports easy recording of onscreen activity, Keynote slides, camera video, microphone, and system audio.
As an example, you can record in front of a live audience and then edit at your desk. You can then export it as an HD video file at a modest file size to share on video sites like YouTube and Vimeo, Apple devices, your website, blog, or anywhere you like.
Camtasia is commercial software, so that's a definite drawback if you're looking for a free solution. Luckily, there are plenty of free Camtasia Studio alternatives with positive feedback from other AlternativeTo users!
